What Will what is the maximum angular velocity with which the turntable can spin without the coin sliding? Be Like in 100 Years?

The angular velocity of the turntable has a rather arbitrary maximum value, which is determined by the angle between the two arms of the turntable.

At first glance, this question seems pretty silly. You can’t really spin the turntable at more than about 60° without the coin sliding! But in reality, it’s a very important question. The turntable will only spin at a maximum angular velocity if the coin is on the inside of the turntable’s arms. If I were a coin collector, I would get really upset if I saw a coin with any portion of the coin touching the outside of the turntable.

Its also really important to understand that the turntables arms are both fixed, and can rotate at any angular speed. There is the possibility that if the coin has a high enough angle to the turntable’s arms that it could slide out of the way if the turntable’s arm is rotated at a higher speed.

That seems to be what happens in the video. Just before the coin slides it seems like the turntable spins around at a high angular velocity. But then at the point where the coin is sliding the turntable spins at a much slower or lower angular velocity. This means that the coin may be slipping out of the way if the turntables arm is rotated at a higher angular velocity.

So what’s the minimum angular velocity with which the turntable can spin without the coin sliding? The answer is what seems to be the maximum angular velocity with which the turntable can spin without the coin sliding. That seems to be what happens in the video. The coin slips out of the way as the turntable spins at a very slow angular velocity. If the angular velocity of the turntable arm is increased enough the coin may slide out of the way.

That’s a good question. The angular velocity of the turntable will depend on the mass of the coin, the coin’s mass, and the speed of the turntable. If the coin is very heavy, the angular velocity will be very low. If the coin is very light, the angular velocity will be very high.

The mass of the coin will determine the angular velocity. The best way to do this is to measure the mass of the coin. If you have accurate mass scales, you can estimate the mass of a coin. But if you don’t have accurate mass scales there is no way to do this. It will be the mass of the coin that determines the angular velocity. And that is why the coin will drop when the turntable spins.

In our opinion, a turntable with very light coins will spin very rapidly, but lighter coins will spin very slowly. If you are going to play a game where the coin is very light, the angular velocity of the turntable will be very high, but with heavier coins, it will be very low.

The maximum angular velocity of the coin in a standard turntable that has no mass scales is about 80 degrees per second. So we’re talking about a coin that has about 400 grams of mass. You can make a coin that is about 2 times as heavy (about 1,400 grams) but still has about the same angular velocity as a coin without a mass scale.

The idea is that it’s a good idea to try to get a good, light coin spin in one part of the turntable, because you need to have enough mass to keep it spinning in the other part of the turntable. A good coin spin is about 20 degrees per second and that’s much less than the spin of a traditional coin.

Yes, I have a physics background… but I have no idea how to do this calculation. I remember thinking that the maximum angular velocity of any object in physics was about the rotation speed of the object. If I remember correctly, this is not what I thought.
